Piloting Visual Chat in Internet Obesity Treatment (CHAT)
2018年12月5日 更新者：Jean R. Harvey, PhD, RD、University of Vermont
CHAT is an internet-based weight loss research program designed for women with overweight or obesity who want to lose weight through dietary change and increased physical activity.
Participants will be randomized into a group-based online program who meet via a text chat or a video chat.
調査の概要
詳細な説明
The overall goal of this project is to determine whether weight losses can be improved if visual chat and electronic smart scales are added to an established 6-month online weight loss program.
The primary aim is to assess weight change differences between subjects randomized to receive an Internet program alone (with text chat; INTERNET) vs. an Internet program with visual chat and electronic scales (VIDEO INTERNET).
A secondary aim is to evaluate differences in social support experienced by subjects in both conditions.
Overweight and obese adults (n=40) at two study sites (UVM and the University of South Carolina) will be randomly assigned to Internet (n=20) or Video Internet (n=20).
All participants will receive the same 24 week web-based group weight control program which features synchronous facilitated chats and online behavioral tools.
The only difference will be the delivery of the chat (text vs. visual) and the electronic smart scales given to the VIDEO INTERNET group.
Assessments will be conducted at 0, 2 and 6 months and will include measures of body weight, treatment engagement (e.g., attendance, self-monitoring, website utilization), social support and treatment satisfaction.

アクティブコンパレータ：Behavioral Weight Loss + Text chat
Internet delivery of a behavioral weight control program via text in a group format facilitated by an experienced registered dietitian.
Participants will have access to study materials including behavioral weight loss lessons on the study's website.
Participants will weigh themselves daily and report their weight privately (data will only be accessible by research personnel) on the study website.
|
Participants will attend weekly one hour classes on line.
They will type their input and responses within the chat room.
They will record their calorie and fat intake daily and weigh themselves daily.
Interventionists will review the diaries weekly and provide feedback to reinforce or shape new behaviors and to identify high risk situations for problem solving.

実験的：Behavioral Weight Loss + Video chat
Internet delivery of a behavioral weight control program via video in a group format facilitated by an experienced registered dietitian.
Participants will have access to study materials including behavioral weight loss lessons on the study's website.
Participants will be given smart scales to weigh daily, and weight will be transmitted to a secure website accessible only by research personnel.

Weight loss from baseline
時間枠：baseline, 2 months, 6 months
|
The investigators will assess weight change differences between subjects randomized to receive an internet program alone with text chat vs. an internet program with visual chat and bodytrace smart scales.
Weight will be assessed at baseline, 2 months after intervention begins, and at the end of intervention using a calibrated digital scale (Tanita, WB800S) with subjects in street clothes, without shoes.

Attendance at chat
時間枠：6 months
|
The group facilitator will record attendance at chats.
Attendance at chat will be compared by treatment arm.
Rate of attendance is calculated as number of meetings attended out of a total possible 24 meetings over the course of the study.

|
Self monitoring dietary intake
時間枠：6 months
|
Number of weekly journals submitted out of a possible 24 weeks total will give the investigators the rate of self monitoring.
Rates of self monitoring will be compared by treatment arm.

Self monitoring weight
時間枠：6 months
|
Number of daily weights submitted over the course of 24 weeks divided by the possible total of weights will give the rate of weight self-monitoring (7/week x 24 weeks = 168 possible weights).
The VIDEO arm will be provided with BodyTrace electronic scales that report weight to a secure database via cellular connectivity.
Subjects in the TEXT arm will report their weights to their facilitator using their own digital scale at home.
